UIBarButtonItem의 글꼴 변경

UIBarButtonItem의 글꼴 변경

---

나는이 UIBarButtonItem내가에 UIToolbar제목 완료 . 이제 Bold 를 사용하여 글꼴을 기본값에서 "Trebuchet MS" 로 변경하고 싶습니다 . 어떻게해야합니까?

---

UIBarButtonItem은 UIBarItem에서 상속되므로 시도해 볼 수 있습니다

- (void)setTitleTextAttributes:(NSDictionary *)attributes
                  forState:(UIControlState)state

그러나 이것은 iOS5 전용입니다. iOS 3/4의 경우 사용자 정의보기를 사용해야합니다.

---

정확히 말하면, 다음과 같이 할 수 있습니다

[buttonItem setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys: 
    [UIFont fontWithName:@"Helvetica-Bold" size:26.0], NSFontAttributeName,
    [UIColor greenColor], NSForegroundColorAttributeName,
    nil] 
                          forState:UIControlStateNormal];

또는 객체 리터럴 구문으로 :

[buttonItem setTitleTextAttributes:@{
     NSFontAttributeName: [UIFont fontWithName:@"Helvetica-Bold" size:26.0],
     NSForegroundColorAttributeName: [UIColor greenColor]
} forState:UIControlStateNormal];

편의상 Swift 구현은 다음과 같습니다.

buttonItem.setTitleTextAttributes([
        NSAttributedStringKey.font: UIFont(name: "Helvetica-Bold", size: 26.0)!,
        NSAttributedStringKey.foregroundColor: UIColor.green],
    for: .normal)

앱 전체에서 글꼴의 UIAppearance스타일을 지정 하는 데 관심 UIBarButtonItem이있는 사용자는 다음 코드 행을 사용하여 수행 할 수 있습니다.

목표 C :

NSDictionary *barButtonAppearanceDict = @{NSFontAttributeName : [UIFont fontWithName:@"HelveticaNeue-Light" size:12.0], NSForegroundColorAttributeName: [UIColor whiteColor]};
[[UIBarButtonItem appearance] setTitleTextAttributes:barButtonAppearanceDict forState:UIControlStateNormal];

스위프트 2.3 :

UIBarButtonItem.appearance().setTitleTextAttributes(
[
    NSFontAttributeName : UIFont(name: "HelveticaNeue-Light", size: 12)!,
    NSForegroundColorAttributeName : UIColor.white
],
for: .normal)

스위프트 3

UIBarButtonItem.appearance().setTitleTextAttributes(
[
    NSFontAttributeName : UIFont(name: "HelveticaNeue-Light", size: 12)!,
    NSForegroundColorAttributeName : UIColor.white,
], for: .normal)

스위프트 4

UIBarButtonItem.appearance().setTitleTextAttributes(
[
    NSAttributedStringKey.font : UIFont(name: "HelveticaNeue-Light", size: 12)!,
    NSAttributedStringKey.foregroundColor : UIColor.white,
], for: .normal)

또는 특히 하나의 버튼에 대한 사용자 정의 글꼴이있는 경우 단일 UIBarButtonItem (모든 앱 범위에 해당하는 것은 아님)의 경우 :

스위프트 3

let barButtonItem = UIBarButton()
barButtonItem.setTitleTextAttributes([
    NSFontAttributeName : UIFont(name: "FontAwesome", size: 26)!,
    NSForegroundColorAttributeName : UIColor.white,
], for: .normal)
barButtonItem.title = "\u{f02a}"

스위프트 4

let barButtonItem = UIBarButton()
barButtonItem.setTitleTextAttributes([
    NSAttributedStringKey.font : UIFont(name: "FontAwesome", size: 26)!,
    NSAttributedStringKey.foregroundColor : UIColor.white,
], for: .normal)
barButtonItem.title = "\u{f02a}"

Of course, you can change the font & size to whatever you'd like. I prefer to put this code in the AppDelegate.m file in the didFinishLaunchingWithOptions section.

Available attributes (just add them to the NSDictionary):

• NSFontAttributeName: Change font with a UIFont
• NSForegroundColorAttributeName: Change color with a UIColor
• NSShadow: Add a drop shadow (see NSShadow class reference)

(Updated for iOS7+)

In Swift you would do this as followed:

backButtonItem.setTitleTextAttributes([
        NSFontAttributeName : UIFont(name: "Helvetica-Bold", size: 26)!,
        NSForegroundColorAttributeName : UIColor.blackColor()],
    forState: UIControlState.Normal)

---

These are great answers above. Just updating for iOS7:

NSDictionary *barButtonAppearanceDict = @{NSFontAttributeName : [UIFont fontWithName:@"HelveticaNeue-Thin" size:18.0] , NSForegroundColorAttributeName: [UIColor whiteColor]};
    [[UIBarButtonItem appearance] setTitleTextAttributes:barButtonAppearanceDict forState:UIControlStateNormal];

---

Swift3

  buttonName.setAttributedTitle([
        NSFontAttributeName : UIFont.systemFontOfSize(18.0),
        NSForegroundColorAttributeName : UIColor.red,NSBackgroundColorAttributeName:UIColor.black],
                                     forState: UIControlState.Normal)

swift

   barbutton.setTitleTextAttributes([
        NSFontAttributeName : UIFont.systemFontOfSize(18.0),
        NSForegroundColorAttributeName : UIColor.redColor(),NSBackgroundColorAttributeName:UIColor.blackColor()],
        forState: UIControlState.Normal)

Objective-C

     [ barbutton setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
        [UIFont fontWithName:@"Helvetica-Bold" size:20.0], NSFontAttributeName,
        [UIColor redColor], NSForegroundColorAttributeName,[UIColor blackColor],NSBackgroundColorAttributeName,
        nil]
        forState:UIControlStateNormal];

In Swift 4, you can change the font and colour of UIBarButtonItem by adding the following code.

addTodoBarButton.setTitleTextAttributes(
        [
        NSAttributedStringKey.font: UIFont(name: "HelveticaNeue-Bold", size: 17)!,
        NSAttributedStringKey.foregroundColor: UIColor.black
        ], for: .normal)

---

To do this for some UIBarButtonItems but not all I recommend the following approach.

1. Create a UIBarButtonItem subclass. Don't add anything to it - you will only use it as a custom class in the storyboard and for its appearance proxy...
2. In your storyboard, change the custom class for all desired UIBarButtonItems to your subclass
3. In your AppDelegate import your UIBarButtonItem subclass and add the following line to application:didFinishLaunchingWithOptions:

In my case I subclassed UIBarButtonItem for the sole purpose of bolding the text:

[[BoldBarButtonItem appearance] setTitleTextAttributes:
  [NSDictionary dictionaryWithObjectsAndKeys: 
    [UIFont boldSystemFontOfSize:18.0], NSFontAttributeName,nil] 
                                              forState:UIControlStateNormal];

---

swift 3

barButtonName.setTitleTextAttributes( [NSFontAttributeName : UIFont.systemFont(ofSize: 18.0),NSForegroundColorAttributeName : UIColor.white], for: .normal) 

---

This is the right way: declare your barButtonItem (in this case rightBarButtonItem) and add it setTitleTextAttributes.

navigationItem.rightBarButtonItem = UIBarButtonItem(title: "Go!", style: .plain, target: self, action: #selector(yourFuncDestination))

after you can add title attributes

navigationItem.rightBarButtonItem?.setTitleTextAttributes([.font : UIFont.systemFont(ofSize: 18, weight: .bold), .foregroundColor : UIColor.white], for: .normal)

you can change the size, the weight (.bold, .heavy, .regular etc.) and the color how you prefer... Hope this help :)

---

Throughout App:

if let font = UIFont(name: "AvenirNext-DemiBold", size: 15) {
        UIBarButtonItem.appearance().setTitleTextAttributes([NSFontAttributeName: font,NSForegroundColorAttributeName:TOOLBAR_TITLE_COLOR], forState: UIControlState.Normal)

    }

UIBarButton haven't property related to change the font. But you can create a button with custom font and then add into UIBarButton. It May be solved your problem

---

Assuming you want to support iOS4 and earlier, your best bet is to create a bar button using the initWithCustomView: method and supply your own view which could be something like a UIButton where you can easily customise the font.

You can also drag a UIButton onto a toolbar or navigation bar in Interface Builder if you want to create the button with drag-and-drop instead of programmatically.

Unfortunately this means creating the button background image yourself. There's no way to customise the font of a standard UIBarButtonItem prior to iOS5.

---

You can create a custom UIView programmatically:

UIView *buttonItemView = [[UIView alloc] initWithFrame:buttonFrame];

Then add images, labels or whatever you like to your custom view:

[buttonItemView addSubview:customImage];

[buttonItemView addSubview:customLabel];

...

Now put it in your UIBarButtomItem.

UIBarButtonItem *barButtonItem = [[UIBarButtonItem alloc] initWithCustomView:buttonItemView];

And finally add barButtonItem to you navigation bar.

완료를 위해 2019 년 Objective-C에서 여전히 사용되는이 방법을 추가하고 싶습니다. :)

_titleLabel = [[UILabel alloc] initWithFrame:CGRectZero];
_titleLabel.text = _titleBarButtonItem.title;
_titleLabel.textColor = UIColor.whiteColor;
_titleLabel.font = [UtilityMethods appFontProDisplayBold:26.0];

[_titleLabel sizeToFit];
UIBarButtonItem *titleLabelItem = [[UIBarButtonItem alloc] initWithCustomView:_titleLabel];
